Yesterday, w/ no media availability or even press release, ERCOT released its Capacity, Demand & Reserves (CDR) report. As has been a pattern lately, the communications with the public about issues of widespread conern is sorely lacking. #txlge 1/🧵

kvue.com/article/news/l…
Just this week, ERCOT CEO Brad Jones, in an article about political interference at ERCOT, said releasing a similar report (the Seasonal Assessment of Resource Adequacy, or SARA) in the same way was a "mistake." But nothing seems to have changed. 2/
texastribune.org/2021/12/28/tex…
The difference betw than the SARA & CDR is that the SARA looks at the upcoming season while the CDR looks several years out.

3 main takeaways:
(1) absent changes, these reports aren't useful
(2) climate change isn't considered
(3) renewables are increasing reliability

@PUCTX meeting starts in a few minutes (9:30CT). Lots of agenda items, including one (#52373) on the future of the ERCOT electric market w/ major customer cost and reliability implications. I'll tweet about it here.
Livestream here: adminmonitor.com/tx/puct/open_m…
#txlege #txenergy
I put together two threads on the staff memo with the proposed changes.
For reference, the memo is here: interchange.puc.texas.gov/Documents/5237…
Explanation of Phase 1 proposals here
Explanation of Phase 2 proposals here:

#energytwitter
There are lots of members of the public in the room with what appear to be paper mache power lines (hard to tell from the feed). Public comment period was changed to 10:30, would normally be at 9:30.

Market design changes will be discussed at the end of the meeting.

Texas' electric market is undergoing a redesign. The implications for everyone in ERCOT w/ an electric bill are huge. I'll translate the jargon in the PUC memo filed this week, summarize key points & describe market participants' reactions. 1/🧵 #txlege #energytwitter
As always, if I got something wrong or if I've misrepresented something (esp. if you're reading this & I've mis-characterized your position), please DM me & I'll correct it. I'm learning & appreciate the constructive criticisms. PUC memo is here:
interchange.puc.texas.gov/Documents/5237…
#txlege
The memo is from staff but is quite obviously reflective of Chairman Lake's position. The first thing in it is Operating Reserve Demand Curve (ORDC). This was created after the 2011 winter outages (and near misses that summer). It adds $ for generators in scarcity conditions.

1, #Germany's new government's #coalitionagreement of the @SPDbt, @Die_Gruenen and @FDP, on the #EuropeanEunion's #EasternNeighborhood: "We are working together with the #EU and its member states on the further development of the #EasternPartnership.
2. States such as #Ukraine, #Moldova & #Georgia, which are striving to join the EU, should be able to move closer through consistent rule-of-law and market-economy reforms. We will react decisively and reliably to democratic upheavals and be a partner to the democracy movements.
3. We want to facilitate civil society exchanges through targeted visa facilitation. We will continue to support Ukraine in restoring full territorial integrity and sovereignty. @UkrVerstehen @H__Ukraine @PromoteUkraine @NEC_Ukraine @intercourier_ua @UaPosition @CPD_UA @gazeta_ua

Big day @PUCTX as two new concepts are introduced & discussed by Commissioners and stakeholders:

*Dispatchable Energy Credits from Cmsr McAdams
*Strategic Reserve Service from Cmsr Cobos

I'll tweet about it on this thread and put some key links below. #txlege #energytwitter
The dispatchable energy credits would come from a kind of Dispatchable Portfolio Standard akin to the Renewable Portfolio Standard and renewable energy credits. There are traded RECs for renewables, there could be traded credits for DECs soon.
interchange.puc.texas.gov/Documents/5237…
Cmsr Cobos proposal is to take a phased approach with a lot of quick actions to increase resilience and reliability while building toward a Strategic Reliability Service, mostly designed for winter, which is described here:

There are public comments today. Haven't heard any public comments in many months. Emma Pabst speaks eloquently for #energyefficiency #demandresponse and public participation. Calls for a meeting targeted to helping the public understand what's going on at the @PUCTX
Misty O'Quinn not testifies to @PUCTX says her daughter had asthma during the outages and couldn't power her medical equipment. Called 911 but no one could come. Had to "slide" to the hospital to get help but they were on generators and it was cold there

"This shouldn't happen."

ERCOT's Jones tells Carrollton City Council: Generation fleet lost 50,000MW because of equipment failure and lack of fuel supply. That's equal to all of California's peak and was more than half of Texas' entire generation fleet.
#txlege #txenergy
When we lose supply, we have turn to the load side to keep balance. We turn to large facilities that have given us the ability to turn down their usage. (he's talking about #demandresponse which we need more of!!!) Once that's exhausted we have to turn off residential customers.

The #GlobalMethanePledge is being launched now at COP26. Result of a massive diplomatic effort by the #EU and the #US, the pledge has now joined over 80 signatories, covering over 2/3 of the global GDP and about 46% of the global #methane emissions. 1/8 unfccc-cop26.streamworld.de/webcast/high-l…
The signatories pledge to cut 30% of global CH4 emissions by 2030, targeting all major emitting sectors #agriculture, #waste, #energy. This is a major step forward & the first time CH4 made it to the top of Global Leaders' priorities list. Many more steps needed looking ahead 2/8
The pledge covers emissions that can be reduced via targeted measures - a lot, but not enough to keep CH4 emissions aligned with 1.5C goal. another 10-15% of reductions must take place via indirect measures incl. #energyefficiency and changes in energy consumption patterns 3/8

Hey, maybe we should all install one of these in our homes?🤔 A heat pump!
A heat pump extracts heat from the cold outside air and transfers it inside our home...

... To this end, a compressor inside the device uses electricity to increase the temperature of the heat extracted from the outside air. The heat pump can also provide cooling by transferring warm indoor air to the outside.

Starting now. After brief opening statement by Chair Schwertner. Sen @whitmire_john asks why do we have to incentivize power plants to do what they're supposed to? Sen Nichols says they're profit seeking companies and they won't invest unless they can make money.
Whitmire responds: are you talking about providing government subsidies for gas generation? Tells Nichols he's sounding like the Biden Administration. Not sure why we would throw incentives at thermal generation.

#txlege #txenergy
Whitmire says we've reshuffled boards and commissions but we may be worse off now in terms of energy reliability than we were in February.

@AEPTexas said they had 11 critical load customers before the storm in Feb, 171 now. 160 facilities didn't fill out a 2 page form pre-Feb. Wow.


This adds new detail to this from @byjayroot @jblackmanChron @Dexinvestigates #txlege houstonchronicle.com/politics/texas…
@TNMP had 2 gas facilities registered as critical infrastructure before the storm. Now has 177. This really is stunning. They're a small player but have a significant Permian footprint.

Texas' energy woes will persist, and costs will be higher, unless demand side resources like #energyefficiency and #demandresponse, #solar and #storage, are deployed at scale. Alison Siverstein wrote a great piece in @UtilityDive about this. A quick 🧵

utilitydive.com/news/fix-texas…
Silverstein is a former FERC & PUC staffer w/ decades of energy experience. She wrote that Texas policymakers and the @PUCTX and @ERCOT_ISO need to "shore up grid reliability by aggressively managing electricity demand, not just throwing money at supply-side measures." #txenergy
She writes that over the last decade TX population increased 16% while energy use increased 20%. Much of that increase is driven by inefficient homes & buildings. We have #energyefficiency programs in Texas that deliver savings at 1 penny per kWh. Try to buy energy for that!

Here we are ! Finally, after 18 months of big talks and long-term objectives about #EUGreenDeal, @EU_Commission releases its mammoth package #FitFor55 #FF55.
Here is my key take-aways: the good, the bad, the ugly. #Thread 👇
Good 1: that’s a massive policy push to transform #EUGreenDeal promises into concrete actions to change our ways of life. @FransTimmermans recognises this will be “bloody hard”, but righly underlines that our future depends on it.
Good 2: Creation of the Social Climate Fund that we @DelorsInstitute have been calling for years. This Fund should start as of 2025 with EU budget, and could invest up to 70Bn€ from 2025 to 2032 to finance national plans to ensure social justice in the transition. #EnergyPoverty

So an update thread on this...I bought a smart controller for my AC, per the suggestion from @Silmarillion88 .

It was pretty easy to install...just plug the device into the wall and plug the AC into the device. Then you download the manufacturer's app and pair with the device. Image
Now I can control my AC from my phone, which is sweet for reducing energy usage.

I like coming home to a nice cool apartment, but I don't want to leave the AC running all day while out.

Last night I turned it on while landing at SZ airport and watched my AC work from the taxi.
Here's the interface from my phone (took this picture right after I turned it on yesterday).

It even gives me two pieces of information I can't get from my AC remote: the current indoor temperature and the power draw in watts. Image

(1/5) Thread: Some good utility-side #electrification insights from @ICF: icf.com/insights/energ…
(2/5) In an @ICF study of 2050 #decarbonization pathways for NYC buildings, #energyefficiency and #electrification are both substantial contributors… in all scenarios providing ~60% of the total decarbonization potential. The point: We must do *both* to be successful!
(3/5) In an @ICF study of 2050 #decarbonization pathways for DC, the 2050 annual peak demand shifts from summer to winter, increasing ~50% in the electrification case relative to BAU, while total annual kWh sales also increase by 22%.

#hb4492 in the Senate.

@RolandForTexas asks Chairman Hancock for a commitment to pursue a ratepayer assistance program. He commits. Bill passes 26-5.

Patrick says he wants this on the special session call.

#TxLege #txenergy
Patrick says he will only work on these things if we're helping ratepayers. Great.

He's indignant about House not taking ratepayer assistance program which was only brought up in the last few days. It's been 100 days since the storm. Where was this proposal in April/early May?
It makes sense to help ratepayers. The Senate had #SB243 to increase #energyefficiency programs which helps customers to save money AND make their homes more resilient. Never got out of committee. The House had #HB3460, the Power Act, to give direct payments to Texans

#SB3 and #HB4492 conference reports are filed. I'll add thoughts to this 🧵as I go through them over the next hour or so.

#txlege #txenergy
#SB3 Headlines:
- Weaker gas regs (House version) are IN the bill.
- Most egregious anti-renewable language is OUT of the bill.
- one minor #demandresponse provision kept IN the bill
- #energyefficiency and most local power gen/storage backup OUT of the bill.
more details soon
Conf report kept House language that required gas supply to be mapped by the Electricity Supply Chain Mapping Committee before any regs are created. Cmte report due 1/1/22, @txrrc rules 6 months later. There will be no gas regulations required before this coming winter.
